  A novel synthetic approach to pyrrolo[2,3-d]pyrimidine antifolates

  摘要：

  A novel and efficient synthetic method for the synthesis of pyrrolo[2,3-d]pyrimidine antifolates is described. The key reaction of this method is the photo-initiated free radical addition of bromomalononitrile or ethyl bromocyanoacetate to an enol ether to afford the backbone skeleton of the targeted antifolate molecule. The key intermediates 3 or 4 are smoothly converted to the pyrrolo[2,3-d]pyrimidine antifolates 1 or 2 in three steps and in high overall yield.

  A One-Step Ring Transformation/Ring Annulation Approach to Pyrrolo[2,3-d]pyrimidines. A New Synthesis of the Potent Dihydrofolate Reductase Inhibitor TNP-351

  摘要：

  Condensation of amidines with 2-amino-3-cyanofurans gives 2-substituted-4-aminopyrrolo[2,3-d]-pyrimidines by a ring-opening, ring-recyclization sequence of reactions through which the starting furan 2-amino nitrogen becomes the pyrrole nitrogen of the final product and one of the amidine nitrogens becomes N-1 of the fused pyrimidine ring. 2,4-Diamino-5-[2-(4-carbethoxyphenyl)ethyl]- pyrrolo[2,3-d]pyrimidine, a key intermediate in the synthesis of the DHFR inhibitor TNP-351, has been prepared in one step by reaction of ethyl 4-[2-(2-amino-3-cyanofuran-4-yl)ethyl]be with guanidine.
